Chrome: We've mentioned lots of ways to keep your bookmarks in sync across browsers and across computers, but if your bookmarks are older than your choice of browser, it might be time to clean them up, get rid of any duplicates you may have, and get rid of any old, dead links that you may have lurking in an old bookmarks folder from way back. Bookmark Sentry for Chrome does just that.

Bookmark Sentry can scan your bookmarks on-demand to clean them up, or be configured to scan them on a regular basis (the default is every 2 weeks, but you can set it anywhere between daily and every other month. You can also tell the tool to scan just for duplicate bookmarks, bad links, or both, and set the connection timeout length before the tool decides a link is dead. When it's finished scanning, it'll present you with a list of dead links and dupes so you can test them to make sure they're really dead and decide which ones you want to delete.

Aside from that, Bookmark Sentry is a simple utility that fills a very basic need. If your bookmarks are a little out of control or need some pruning, this extension will take care of them. Do you have an alternative you prefer, or do you not bother with bookmarks in your browser anymore? Let us know in the comments below.
